Photophysical studies and submicron ring formation of morpholino U-nucleoside monomers†
Abstract
Synthesis, photophysical properties and submicron ring formation of functionalized uracil morpholino monomers have been reported. A series of characterization techniques indicated that the rings are formed by the inter-molecular hydrogen bonding of the uracil nucleus having a trityl-protected morpholino moiety. This is the smallest nucleoside unit known to date for submicron size ring formation.
