Donor-Acceptor Conjugated System: A Neutral Hydrophobic Fluorescence Probe

Abstract

Fluorescence probe with intramolecular charge transfer behavior has received a great deal of attention in recent years Such molecule is highly sensitive to its local environment and plays critical role in many industrial and biological applications Donor acceptor conjugated systems based on diphenylpolyene are one of such example The presence of conjugated chain length and the donor acceptor substituent rsquo s at the appropriate position allows the molecule to cover a wide range of absorption and fluorescence wavelength and hence the optical property of the molecule is attenuated easily Thus diphenylpolyenes are suitable candidate for various fluorescence probe applications The above mentioned aspects have been discussed and summarized in this paper
