A new triisopropylsilylethynyl anthracene derivative was synthesized with extended aromatic groups at the 2- and 6-positions of anthracene for application in a high-performance photodetector. When operated at room temperature under ambient conditions, the photodetector based on a single crystal showed a sensitive response to green light, with a responsivity of 4 A/W and a specific detectivity of 4.1 × 1011 Jones. Based on a systematic analysis of the photocurrent behavior as a function of the optical power and the applied bias, the operating mechanism of the photodetector was found to be a gain-generation process with a high photoconductive gain of 400. |
