trichloride/trimesoyl chloride (TMC) core, are reported. T0 does not have any replaceable H+ on its terminal phenyl group, acting as a branch. T1 has one phenolic –OH at the para position and T2 has two phenolic –OH groups at the 3 and 5 positions of each terminal phenyl group. During synthesis, these –OH groups at the terminal phenyl groups were protected through tert-butyldimethylsilyl chloride (TBDMSCl) assisted
三邻甲苯基苯-1,3,5-三羧酸酯 (TOBT ( T0 ))、三-4-羟基苯基苯-1,3,5-三羧酸酯 (THBT ( T1 )) 和三-3,5-二羟基苯基报道了苯-1,3,5-三羧酸酯 (TDBT ( T2 ) ),这是一系列具有共同 1,3,5-苯三羰基三氯化物/均苯三甲酰氯 (TMC) 核心的一级树枝状大分子。T0在其末端苯基上没有任何可替换的 H + ,作为一个分支。T1在对位有一个酚-OH,T2在每个末端苯基的 3 位和 5 位具有两个酚基 -OH 基团。在合成过程中,末端苯基的这些 -OH 基团通过叔丁基二甲基甲硅烷基氯 (TBDMSCl) 与t -BuOK 在 DCM、THF、吲唑、4-二甲基氨基吡啶 (DMAP) 和叔丁基氟化铵 ( TBAF)。MTBDMSP(单叔丁基二甲基硅烷间苯三酚)、DTBDMSP(二叔丁基二甲基硅烷间苯三酚)和 TTBDMSP(三叔丁基二甲基硅烷间苯三酚)的收率
