In addition, the properties of the luminescence
derived from gold complexes are structure-dependent4 such
that colour and/or luminescence intensity can be manipulated
by control of the aggregate structure.5 So far, several types of
liquid-crystalline (LC) gold complexes have been developed with
the aim of controlling their aggregate structure.6 Some useful
characteristics of LCs that lend themselves to efficient aggregate
control include their self-assembled nature, uidity, and
responsivity to external stimuli.7 In this study, we examine the
aggregation and photoluminescence behaviours of gold
complexes in both crystalline and LC phases, providing a
discussion of the relationship between the aggregated structure
and luminescence properties. In particular, we report that a
reversible change in the luminescence colour can be induced by
precise control of the aggregate structure.
