Photonic materials include light-emitting organic oligomer compositions
that include at least one light-emitting oligomer. The oligomer
compositions include oligofluorenes having chiral and/or achiral
pendants. The oligomer compositions also include spiro-linked
oligofluorenes and fully spiro-configured terfluorenes. Methods for
syntheisizing light-emitting organic oligomer compositions include
preparing fluorene-based oligomers by convergent/divergent synthesis.
