ethylenediamine spacer using a succinct synthetic route to give a bromoacridine-linked, bifunctional fluorophore conjugate for the detection of triplex DNA. Acridine is well known to intercalate into duplex DNA whereas introduction of a bulky bromine atom at position C2 redirects specificity for triplex over duplex DNA. In this work, photoelectron transfer assay was used to demonstrate that the synthesised

AbstractEfficient synthesis of fluorescent probes based on 1,8-naphthalicanhydride from acenaphthene with the help of microwave irradiation is described. Application of microwave dielectric heating helped improve the yield of the products (>85%) and also reduced the formation of undesired side-products. Graphical Abstract

A new Zn 2 + fluorescent sensor NIDPA (1) which takes 1,8-naphthalimide as a reporting group and di-2-picolylamine (DPA) as a recognizing group has been synthesized via simple steps. Based on photo-inducedelectrontransfer (PET) mechanism, NIDPA has a nearly 5-fold fluorescent enhancement under simulated physiological conditions corresponding to the binding of Zn 2 + .
