Section 1. Materials and methods.
All manipulations involving air and/or moisture-sensitive compounds were carried out under a nitrogen
atmosphere (ultra-high purity) using either standard Schlenk techniques or glove box techniques.
Solvents were dried and distilled using standard procedures. Reagents were purchased and used as
received without further purification. ZrCl4(THF)2[S1], Ph3CB(C6F5)4[S2], 2-tert-butyl-4-
acetylphenol[S3] and complex 3 bis[N-(3-tert-butylsalicylidene)-cyclohexylaminato]zirconium (IV)
dichloride [S4] were prepared according to literature procedures. Polymerization grade ethylene was
further purified by passage through columns of 5 A molecular sieves. 1H and 13C NMR spectra were
recorded on a Varian Mercury-300 NMR spectrometer, where chemical shifts (δ in ppm) were
determined with a residual proton of the solvent as standard. Solid-state 13C CP/MAS NMR
measurements were recorded on a Bruker AVANCE III 400 WB spectrometer at a MAS rate of 5 KHz
and a CP contact time of 2 ms. Infrared spectra were recorded from 400 to 4000 cm-1 on a Nicolet FT-
IR 360 spectrometer by using KBr pellets. ESI-MS was carried out on a Thermo Fisher ITQ1100 ion
trap gas chromatography-mass spectrometry. Elemental analyses were carried out on an Elementar
model vario EL cube analyzer. Field emission scanning electron microscopy was performed on a
SU8020 model HITACHI microscope. The Zirconium contents in polymer frameworks were
determined by Perkin-Elmer ICP-OES Optima 3300DV spectroscopy. Powder X-ray diffraction data
were recorded on a PANalytical BV Empyrean diffractometer by depositing powder on glass substrate,
from 2θ = 4.0° to 40° with 0.02° increment at 25 oC. Thermogravimetric analysis (TGA) was performed
on a TA Q500 thermogravimeter by measuring the weight loss while heating at a rate of 10 oC min−1
from 25 to 800 oC under nitrogen. Nitrogen sorption isotherms were measured at 77 K with a JW-BK
132F analyzer. Before measurement, the samples were degassed in vacuum at 150 oC for more than 10
h. The Brunauer-Emmett-Teller (BET) method was utilized to calculate the specific surface areas and
pore volume, the Saito-Foley (SF) method was applied for the estimation of pore size distribution. The
molecular weight and molecular weight distribution of the polymer samples were measured on a PL-
GPC 220 at 140 oC with 1,2,4-trichlorobenzene as the solvent. The melting points of the polymer were
measured by differential scanning calorimetry (DSC) on a NETZSCH DSC 204 at a heating/cooling rate
of 10 oC min-1 from 35 to 180 oC and the data from the second heating scan were used.
Section 2. Synthetic procedures.
Synthesis of 1,3,5-Tris(3’-tert-butyl-4’-hydroxyphenyl)benzene
2-tert-butyl-4-acetylphenol (2.3 g,12 mmol) was dissolved in 25 mL dry ethanol. Then SiCl4 (6.9
mL, 60 mmol) was added to it at 0 oC. The mixture was stirred at 0 oC for 30 min and at room
temperature overnight. The reaction mixture was quenched with water and extracted 3 times with

Synthesis of 1,3,5-Tris(3’-tert-butyl-4’-hydroxy-5’-formylphenyl)benzene (TBHFPB)
To a stirred mixture of anhydrous magnesium dichloride (2.0 g, 21 mmol) and solid
paraformaldehyde (0.96 g, 31 mmol) in dried THF was added 3 mL of triethylamine dropwise and the
mixture was stirred at room temperature for 10 min. A solution of 1,3,5-Tris(3’-tert-butyl-4’-
hydroxyphenyl)benzene (1.85 g, 3.5 mmol) in THF was added dropwise. Then the mixture was heated
to reflux for 4h. After the reaction mixture was cooled to room temperature, 50 mL of ethyl acetate and
50 mL of 1N HCl were added. The organic phase was separated and washed with 1 N HCl (2×100 mL)
and water (3 × 100 mL), dried over MgSO4, and filtered. The solvent was removed by rotatory
evaporation to leave the crude product which was purified by column chromatography on silica gel
using petroleum ether/CH2Cl2(3: 1) mixture as the eluent to give the title compound 1.33 g, yield 62%.

General procedure for synthesis of Cat 1a-c and Cat 2a-b
In a typical procedure, NaH (40 mg, 1.7 mmol) was added to a THF (CH2Cl2 or dioxane) solution
of 0.5 mmol of L1H3 (or L2H3) . The solution was vigorously stirring at room temperature for 12 h. Then
ZrCl4(THF)2 (0.75 mmol) was added, and the reaction mixture was refluxed for 3 days. The precipitate
was collected by filteration, washed and dried under vacuum for 12 h. The self-immobilized catalysts
1a-c and 2a-b were obtained in 70~85% yields.
Ethylene polymerization experiments
A dry 250 mL steel autoclave with a magnetic stirrer was charged with 50 mL of toluene, and
saturated with ethylene (1.0 bar). The autoclave was kept in a water bath at a corresponding
temperature. The polymerization reaction was started by injection of a mixture of AlR3, Ph3CB(C6F5)4
and a catalyst suspended in toluene (10 mL). The vessel was repressurized to the needed pressure with
ethylene immediately, and the pressure was kept by continuously feeding of ethylene. After a certain
period of time, the polymerization was quenched by injecting acidified methanol (HCl (3 M)/methanol
1/1). The polymer was collected by filtration, washed with water and methanol, and dried at 60 oC in
vacuo to a constant weight. Most of the PCP catalyst should be retained in the polymer due to its
insolubility in water and common organic solvents.
