Tunable SiN Hybrid Conjugated Materials

Tunable conjugated polymers for bacterial differentiation

A novel rapid method for bacterial differentiation is explored based on the specific adhesion pattern of bacterial strains to tunable polymer surfaces. Different types of counter ions were used to electrochemically fabricate dissimilar polypyrrole (PPy) films with diverse physicochemical properties such as hydrophobicity, thickness and roughness. These were then modulated into three different o...

Hybrid Optoelectronic and Photovoltaic Materials based on Silicon Nanocrystals and Conjugated Polymers

Conjugated Polymer-Based Hybrid Materials for Turn-On Detection of CO2 in Plant Photosynthesis.

Detection of carbon dioxide (CO2) is of fundamental importance in diverse applications ranging from environmental analysis to agricultural production. In this work, a hybrid probe based on guanidinium-pendent oligofluorene (G-OF) and water-soluble conjugated polythiophene (PTP) has been developed for the turn on detection of CO2 with low background signal, taking advantage of the efficient fluo...

Exciton dissociation and migration in enhanced order conjugated polymer/nanoparticle hybrid materials

The mechanisms of exciton dissociation and migration in the conjugated polymer (poly(2-methoxy-5-(2′-ethyl)(hexyloxy)1,4phenylenevinylene))(MEH-PPV)/CdSe nanoparticle hybrid materials were investigated by steady-state and time-resolved photoluminescence spectroscopy. Rapid exciton dissociation at the nanoparticle/polymer interfaces, leading to quenching of the photoluminescence efficiency η and...
