Abstract
A unique fluorescence resonance energy transfer (FRET) process is found to be operational in a unilamellar lipid self-assembly in the aqueous phase. A newly synthesized naphthyl based long chain lipid derivative [N-(naphthalene-1-ylmethyl)tetradecane-1-ammonium chloride, 14NA+] forms various self-assembled architectures in the aqueous phase. Controlled changes in lipid concentration lead to a transition of the self-assemblies from micelles to vesicles to rods. In the presence of cucurbit[7]uril (CB7), 14NA+ forms a host-guest [2]pseudorotaxane complex (CB7∋14NA+) and secondary interactions lead to the formation of a lipid bilayer with hydrophobic pockets situated in between the layers. The change in the structure of 14NA+ assemblies, interaction with CB7 and formation of supramolecular assemblies of CB7∋14NA+ were examined using light scattering, spectroscopic, and microscopic techniques. Entrapment of a luminescent dye, anthracene within the hydrophobic bilayer of the supramolecular assembly CB7∋14NA+ favors a modified luminescent response due to an efficient FRET process. Further, the FRET process could be controlled by thermal and chemical stimuli that induce transformation of unilamellar vesicles.

Abstract
The power efficiency of a diode-pumped solid state laser was improved by encasing the Nd:YAG lasing medium with gold nanorod-doped epoxy. Gold nanorods were synthesized with a specific aspect ratio tuned to absorb at the Nd:YAG lasing wavelength of 1064 nm. The surfactant-stabilized nanorods in aqueous solution were then treated with a sequential, two-step functionalization in order to improve nanorod solubility in organic solvents. This process required treating the gold nanorods with a thiol-containing polyethylene glycol (PEG) polymer followed by replacing the PEG-SH polymer with a multidentate thiol containing block copolymer synthesized using RAFT synthesis. With a multidentate polymer, the nanorods were soluble in traditional epoxies that could be used to coat the outside of Nd:YAG rods. By absorbing excess lateral 1064 nm emission, the gold nanorod coating attenuates amplified spontaneous emission (ASE), a parasitic, incoherent process that limits power produced by Q-switch laser designs. Laser power increased by nearly 2-fold with addition of the 1064 nm absorbing gold nanorod coating. Gold nanorod epoxy coatings stand out as attractive materials for attenuating ASE by avoiding the fabrication difficulties of samarium oxide ceramics and the photostability limitations of organic dyes.

Abstract
A novel kind of supramolecular free radical with significantly improved free radical yield and enhanced near-infrared (NIR) photothermal conversion has been fabricated. Perylene diimide (PDI) can undergo chemical reduction to generate PDI radical anions. Cucurbit[7]uril (CB[7]), a bulky hydrophilic head, was utilized to encapsulate the two end groups of the PDI derivative via host-guest interactions, thus hindering its aggregation and suppressing the dimerization and quenching of PDI radical anions in aqueous solution. Due to the increased concentration of radical anions and their absorption above 800 nm, the efficiency of NIR photothermal conversion was significantly improved. Compared with free radicals fabricated by covalent chemistry, the supramolecular free radicals established here could provide a facile approach for the promoted formation of aromatic free radicals, thus opening up a new strategy for the design of NIR photothermal materials with enhanced photothermal conversion.
