标 题 :De novo synthesis of bacteriochlorins
发明人：KIM HAN-JE; LINDSEY JONATHAN S
权利人:UNIV NORTH CAROLINA STATE
摘要:A method of making a bacteriochlorin is carried out by condensing a pair of compounds of Formula II n nto produce the bacteriochlorin, wherein R is an acetal or aldehyde group. The condensing may be carried out in an organic solvent, preferably in the presence of an acid. The bacteriochlorins are useful for a variety of purposes such as active agents in photodynamic therapy, luminescent compounds in flow cytometry, solar cells, light harvesting arrays, and molecular memory devices.

摘要:The invention relates to the synthesis of polymers containing self-complementary quadruple hydrogen groups by copolymerizing monomers containing a quadruple hydrogen bonding group with one or more monomers of choice. The resulting polymers show unique new characteristics due to the presence of additional physical interactions between the polymer chains that are based on multiple hydrogen bonding interactions (supramolecular interactions).
