were dissolved in dry THF (10 mL) and degassed/purged with N2. To this,
Pd(PPh3)4 (0.03 mmol, 33mg) was added followed by aq. K2CO3. The
reaction mixture was refluxed for 24 h and cooled to room temperature.
The mixture was added to water and extracted with DCM and filtered
over Na2SO4. The solution was concentrated under reduced pressure to
result in crystalline yellow solid. Yield, 60 %.

Synthesis of F0.0CMP, F0.1CMP, F0.5CMP and F2.0CMP. For
synthesizing F0.0CMP, a mixture of tetrakis(4-bromophenyl)ethene (0.15
mmol, 100 mg) and 1,4-benzenediboronic acid (0.3 mmol, 49 mg) were
taken in a Schlenk tube and dissolved in dry DMF. The reaction mixture
was allowed for freeze-thaw pump cycles and purged with N2
continuously. Pd(PPh3)4 (0.0105 mmol, 12 mg) was added to the mixture
under N2 flow. After that aq. K2CO3 was added to the mixture and
refluxed for 24 h under N2 atmosphere. Precipitates were collected by
filtration and washed with ethanol and THF for several times. Final
purification was done using Soxhelet extraction with THF and methanol
for 48 h each. EDAX: C, 96; Pd, 0.31. Similar reaction procedure was
used for preparing F0.1CMP, F0.5CMP and F2.0CMP, only difference was
0.1 eq (0.015 mmol), 0.5 eq (0.075 mmol) and 2.0 eq (0.3 mmol) of 2,7-
dibromo-9H-fluoren-9-one was added, respectively in to the reaction
mixture containing tetrakis(4-bromophenyl)ethene (0.15 mmol, 100 mg)
and 1,4-benzenediboronic acid (0.3 mmol, 49 mg). In all cases, the
product formed was purified using Soxhelet extraction with THF and
methanol for 48 h.

Photocatalytic hydrogen evolution experiment. Photocatalytic H2
evolution experiments were carried out in a 80 ml stoppered flask. 5 mg
FxCMP is dispersed in 40 ml water containing 0.75 M Na2S and 0.75 M
Na2SO4. The suspension was ultrasonicated to make a homogeneous
dispersion which was later purged with N2 for 30 minutes to remove all
the dissolved gases. The reaction mixture was irradiated with 290 W Xe
lamp (Newport) fitted with 12 cm path length of water filter for removal of
IR radiation. A visible-bandpass filter (400 nm-800 nm) was used to block
the UV-light. The evolved gas was analysed by Agilent CN15343150 Gas
Chromatography which use a thermal conductivity detector referencing
against a standard (H2/N2) gas mixture with a known concentration of
