*Reaction file type CDX
*Procedure In a 50 mL rbf a solution of 1,4-Didodecyl-2,5-bis(2-(4-(2-(4-(2-(trimethylsilyl)ethynyl)phenyl)ethynyl) phenyl)ethynyl)benzene(58 mg, 0.06 mmol) in THF (10 mL: large excess) was stirred for 15 min, at r.t., in presence of TBAF (0.84 mL of a solution 1 M in THF; 14.00 eq.); the disappearance of starting material (Rf 0.00, (20/1) hexane/DCM) was monitored by TLC. The solvent was evaporated and the residue was dissolved in DCM; the solution was washed with water and brine, dried over anhydrous MgSO4 and evaporated, to afford the crude product (bright yellow solid, 56 mg, 0.06 mmol, yield 93%). No further purification was carried out. 
*Yield (%) 93 %
*Type of Yield Reaction yield
