文摘

A series of -conjugated molecular wires based on thienylethynylene units have been developed to understand the effect of the molecularstructures on their photophysical properties. The investigation of their photophysical properties indicates that the formation of aggregates atthe ground state is effectively suppressed by the incorporation of truxene units. The excited-state lifetimes are observed to be biexponentialfor these molecular wires.
