摘要：
We have developed vapor-deposited films of acenaphtho [1,2-k] fluoranthene (AF) and their 7,14-dicarbalkoxy derivatives as active layers of organic field-effect transistors (OFETs). The AF- and 7,14-dicarbmethoxyacenaphtho [1,2-k] fluoranthene (DMAF)-based OFET devices did not work sufficiently. On the other hand. the 7,14-carbethoxyacenaphtho [1,2-k] fluoranthene (DEAF)-based OFET device showed typical p-channel FET responses with a field-effect mobility of 1.7 X 10(-3) cm(2) V(-1)s(-1) and a current on/off ratio of about 10(2). According to the X-ray diffraction measurements. the carbethoxy groups could largely improve the molecular packing that is favorable for high-performance OFETs.
