Cl-BODIPYs: a BODIPY class enabling facile beta-substitution
Lundrigan, Travis; Crawford, Sarah M.; Cameron, T. Stanley; Thompson, Alison (2012-01)Cl-BODIPYs, synthesized in high yields from dipyrrins under air- and moisture-free conditions, are extremely facile to substitution at boron compared to their corresponding F-BODIPYs, opening up a new route to BODIPYs ... -
Dipyrrins, Pyrrolyldipyrrins, Prodigiosenes and Their Complexes
Crawford, Sarah M. (2012-12-20)Dipyrrins, pyrrolyldipyrrins and prodigiosenes are a closely related series of molecules: pyrrolyldipyrrins are dipyrrins with a pyrrolic substituent and prodigiosenes are a special class of pyrrolyldipyrrins with a methoxy ... -
The first series of alkali dipyrrinato complexes
Ali, Adeeb Al-Sheikh; Cipot-Wechsler, Judy; Crawford, Sarah M.; Selim, Omar; Stoddard, Rhonda L.; Cameron, T. Stanley; Thompson, Alison (2010-08)The first series of alkali dipyrrinato complexes is reported, encompassing lithium, sodium, and potassium salts of meso-unsubstituted and meso-aryl-substituted derivatives. By varying the substituents at the meso position, ... -
Investigations into the nucleophilic meso-substitution of F-BODIPYs and improvements to the synthesis of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene.
Crawford, Sarah M.; Thompson, Alison (2011)A series of three F-BODIPYs, with varying levels of steric crowding about the meso-position were selected to investigate nucleophilic meso-substitution of F-BODIPYs. The synthesis of one of these F-BODIPYs, 4,4-difluor ... -
Synthesis and characterisation of the unsubstituted dipyrrin and 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene: improved synthesis and functionalisation of the simplest BODIPY framework
Groves, Brandon R.; Crawford, Sarah M.; Lundrigan, Travis; Matta, Cherif F.; Sowlati-Hashjin, Shahin; Thompson, Alison (2013)An improved and scalable synthesis of the unsubstituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a- ...
