Aggregation/disaggregation properties in organic/inorganic interfaces have been intensively investigated recently because modulation of the aggregation effect can enhance the fluorescent emission, facilitate light scattering and strengthen the material strength. In this study, bisindolo quinoxaline-tips (BIQ-TIPs) organic polymers dropped on ZnO nanorods (NRs) to form organic/inorganic hybrid photosensing materials. Multiple morphological and material characterizations reveal that as-deposited BIQ-TIPs polymers self-aggregated on ZnO NR surfaces. UV/VIS measurements and photoluminescence (PL) mapping indicate that the absorption spectra of ZnO NRs can be broadened by incorporating BIQ-TIPs on top of ZnO NRs. Furthermore, light photosensitive measurements indicate that BIQ-TIPs /ZnO NRs-based devices exhibited better UV sensing behaviors than ZnO NR-based devices. Interestingly, BIQ-TIPs /ZnO NRs still possessed moderate green light sensing capability while ZnO NRs and BIQ-TIPs only samples possessed no green light sensing capability. Owing to their compact size, facile fabrication, and versatility, BIQ-TIPs /ZnO NR devices show promise for integration with BIQ-TIPs analogue-based electronic devices and future broadband sensing and light-harvesting applications.
