Ultrafast photonhyphen;mode recording by novel photochromic polymer via photoinduced electron transfer

摘要

The color change of a novel photochromic polymer film of 4,4rsquo;hyphen;bipyridiniumhyphen;tetrakis lsqb;3,5hyphen;bis(trifluoromethyl)phenylrsqb;borate was shown to occur in less than 20 ps by the pshyphen;laser excitation of an ionhyphen;pair chargehyphen;transfer band due to photoinduced electron transfer, which may be applied to ultrafast photonhyphen;mode recording.
