Charge-transfer inclusion complex formation of the tropylium cation with prism[6]arenes

Herein, we report that prism[6]arenes ( PrS[6] R ) can form charge-transfer (CT) inclusion complexes with tropylium tetrakis[3,5-bis(trifluoromethyl)-phenyl]borate ( G ) in chloroform solution with an obvious CT band at 560 nm. Moreover, the CT complex PrS[6] Et ⊃G showed Cl − /Ag + responsiveness which can be easily monitored by the naked eye. We report that charge-transfer (CT) inclusion complexes were formed between prism[6]arenes and tropylium cation. Additionally, the CT complex showed Cl − /Ag + responsiveness which can be easily monitored by the naked eye.
