通过Suzuki-Miyura偶联反应合成了具有OTBS基团的三联苯衍生物3和4。这些化合物在使用四丁基氟化铵进行OTBS基团的脱保护的同时经历了前所未有的不可逆环化，得到对称/不对称取代的三苯。三联苯3也可作为一种新的氟离子化学剂量计。
Terphenyl derivatives 3 and 4 having OTBS groups have been synthesized via a Suzuki-Miyura coupling reaction, These compounds undergo unprecedented irreversible cyclization to symmetrically/unsymmetrically substituted triphenylenes while carrying out the deprotection of OTBS groups using tetrabutylammonium fluoride. Terphenyl 3 also serves as a new chemodosimeter for fluoride ions.
