•P-zigzags nanoclusters reactivities surpass armchairs and end-edges.•P-armchairs & end-edges may be ideal choices for novel fire-retardant sensors.•P-zigzags compete as upcoming nominees for solar cells & avalanche photodetectors.•N-based P-zigzags are perfect candidates for forthcoming photovoltaic technology.
Opto-tunability is acknowledged for P-nanoclusters via polymeric substituents through electronic, optical, and NLO responses change. Results show that P-zigzags reactivities surpass armchairs and end-edges. P-armchairs and end-edges are ideal choice for fire-retardant-sensors. Whereas P-zigzags compete as upcoming nominees for solar cells andavalanche photodetectors. P-zigzags shows a magnificent NLO response specially forN and S based-polymeric substituents. P-zigzags suffer a blue shift in their absorptions than pure-nanocluster. Delocalized electron pairs associated with N-based P-zigzags push Fermi level close to conduction-zone that induce a denser ESP.Hereby, authors declare that N-based P-zigzags may be the perfect candidates for forthcoming photovoltaic technology.
