Photocontrolled Binding and Binding-Controlled Photochromism within Anthracene-Modified DNA
Modified DNA strands undergo a reversible light-induced
reaction
involving the intramolecular photodimerization of two appended anthracene
tags. The photodimers exhibit markedly different binding behavior
toward a complementary strand that depends on the number of bases
between the modified positions. By preforming the duplex, photochromism
can be suppressed, illustrating dual-mode gated behavior
