Non-linear optical, electrochemical and spectroelectrochemical properties of amphiphilic inner salt porphyrinic systems

Three zwitterionic meso-substituted A(3)B- and AB(2)C-porphyrins containing one sulfonato alkylpyridinium substituent and three or two alkoxy-substituted phenyl groups were synthesized in good yield and fully characterized as to their…

Diameter-selective non-covalent functionalization of carbon nanotubes with porphyrin monomers.

We report on the spontaneous noncovalent functionalization of carbon nanotubes with hydropho-bic porphyrin molecules in micellar aqueous solution. By monitoring the species concentrations with optical spectroscopies, we can follow the kinetics of…

Using Low Temperature Photoluminescence Spectroscopy to Investigate CH$_3$NH$_3$PbI$_3$ Hybrid Perovskite Degradation

Investigating the stability and evaluating the quality of the CH$_3$NH$_3$PbI$_3$ perovskite structures is quite critical both to the design and fabrication of high-performance perovskite devices and to fundamental studies of the photophysics of the…

Side-Chain Metallopolymers Containing Second-Order NLO-Active Bimetallic Ni-II and Pd-II Schiff-Base Complexes: Syntheses, Structures, Electrochemical and Computational Studies

Unsymmetric Schiff-base metalloligand precursor 2 is synthesized by condensation of phenol-functionalized ferrocenylenaminone 1 with 2-hydroxy-5-nitrobenzaldehyde. Heterobimetallic complexes 3 and 4 result from the N2O2-tetradentate coordination of…

Thermodynamics study of the noncovalent functionalization of surfactant suspended graphene nanosheets with porphyrin molecules

We report on the noncovalent functionalization of graphene with hydrophobic tetraphenyl porphyrin (TPP) molecules in micellar aqueous suspensions. We study the thermodynamical parameters of the reaction using optical spectroscopy, and measure its…

Single layer nano graphene platelets derived from graphite nanofibres

Solutions of calibrated nanographenides (negatively charged nanographenes) are obtained by dissolution of graphite nanofibre intercalation compounds (GNFICs). Deposits show homogeneous unfolded nanographene platelets of 1 to 2 layers thickness and…

Coherent Population Trapping of a Single Nuclear Spin Under Ambient Conditions

Coherent control of quantum systems has far-reaching implications in quantum engineering. In this context, coherent population trapping (CPT) involving dark resonances 1,2 has played a prominent role, leading to a wealth of major applications…

Room-temperature exciton coherence and dephasing in two-dimensional nanostructures

Electronic coherence has attracted considerable attention for its possible role in dynamical processes in molecular systems. However, its detection is challenged by inhomogeneous line broadening and interference with vibrational coherences. In…
