- Abstract
- Anthracene-based conjugated molecules are synthesized and J-aggregations are clearly observed in a single-crystal structure study. Single-crystal-based field-effect transistors (FETs) exhibit high field-effect mobility. They display dramatic photoinduced enhancement of the drain current and show unusually high photoresponsivity under extremely low intensity light. Due to the photoinduced enhancement of excitons, single and multiple-stage memory operations are achieved.
