The present paper deals with the photophysical and time resolved spectroscopic investigations performed on the pristine short chain dyad, (E)-4-(((9H-fluorene-2-yl) imino) methyl)-N,Ndimethylaniline (NNDMBF) and its nanocomposite forms with CQD or NCQD. The experimental results with dyad-CQD (or NCQD) demonstrate that more than 80% trans structure of the ground state dyad could be protected in the environment of CQD (or NCQD) even on photoexcitation. Formations of elongated trans-conformers show in favor of efficient energy-storage systems. The stability of extended conformation has been hinted to be due to combination of surface coverage and surface trap effects, the later process seems to be the dominating one.
