Novel nano-dyad of homoleptic sandwich-type phthalocyanines with nitrogen doped graphene quantum dots for nonlinear optics

Abstract

The synthesis and nonlinear optical (NLO) behaviour of three novel double decker sandwich-type phthalocyanine complexes and their conjugates with nitrogen doped graphene dots (NGQDs) were reported herein. The conjugates afforded the most efficient NLO behaviour.

Design consideration of phthalocyanines as sensitizers for enhanced sono-photodynamic combinatorial therapy of cancer

“…Some of the NPs studied in PDT have been reported in SDT alone and as adjuvants for Pcs. Graphitic nanoparticles such as graphene oxide (GO), or graphene quantum dots (GQDs) have been reported to act as donor and promote the transfer of energy to Pcs acceptors through Forster energy resonance transfer (FRET) during PDT 128 , 129 . FRET therefore allows for enhance ROS yields under light exposure.…”

Quantum Confinement of Electron–Phonon Coupling in Graphene Quantum Dots

“…Owing to their quantum-confined band gap, graphene quantum dots (GQDs) exhibit intriguing photoluminescence and photocatalytic properties with potential applications in bioimaging, , photovoltaics, , light-emitting diodes, , and water splitting. , The highly tunable gap of GQDs also renders them as attractive nanomaterials for exploitation in the growing fields of nonlinear optics − and quantum computing. , Similarly to graphene nanoribbons, the gap (ε g ) of pristine GQDs varies inversly proportional with the dot size ( L ), i.e., ε g ∝ 1/ L . This behavior is well-established.…”
