Abstract
We have examined the photon statistics of single tetrahedral based oligophenylenevinylene (TOPV) molecules using photon pair correlation spectroscopy (PPCS). The second-order correlation function g(2)(τ) can be obtained from PPCS and the value of g(2)(τ) at small τ can be used to quantify the number of chromophores involved in emission. Comparison of g(2)(τ) obtained from OPV `armsʹ versus TOPV revealed limited interchromophore coupling in TOPV. Unlike previous studies on interchromophore coupling in organic semiconductors, TOPV molecules are able to sustain simultaneous emission from multiple arms.
