Problems solved by technology

However, the use of this design strategy results in the vast majority of thiacalix[4]arene-based receptor molecules having a symmetrical structure and containing only a single optical or electrical signal responsive group, making it difficult to achieve a dual-channel response using light and electricity. Efficient detection of specific substrates, limiting its range of applications

Abstract

The invention discloses an asymmetric photoelectric active thiacalixarene [4] acceptor molecule and a compounding method thereof. The method is characterized by successfully compounding the asymmetric photoelectric active thiacalixarene [4] acceptor molecule containing ferrocene and rhodamine b groups by successively introducing an electrochemical probe and a fluorescence probe into a thiacalixarene [4] structure platform by utilizing asymmetric design and then performing stepping selective acylation reaction of thiacalixarene [4]-1,3-diamine.
