Direct synthesis of an oligonucleotide-poly(phenylene ethynylene) conjugate with a precise one-to-one molecular ratio.
TLDR
This work introduces a versatile and effective synthetic method for coupling oligonucleotides to conjugated polyelectrolytes and extends this approach to other biomolecules such as biotin by using a similar approach with biotin phosphoramidite.

Amplified quenching of a conjugated polyelectrolyte by cyanine dyes.
TLDR
Steady-state and picosecond time-resolved fluorescence spectroscopy are used to examine amplified quenching of PPESO3 by a series of cyanine dyes via singlet-singlet energy transfer and the results show that PPesO3 to HMIDC energy transfer occurs on two distinctive time scales.

Understanding the dark and light-enhanced bactericidal action of cationic conjugated polyelectrolytes and oligomers.
TLDR
The finding thus show that the antimicrobial polymers and oligomers exert toxicity toward Gram-negative bacteria by disrupting the morphology and structures of cell envelope and cytoplasm, including cellular components such as proteins and DNA, while exert toxicity towards Gram-positive bacteria by binding to and disrupting just the cell wall.

An iridium(III) complex that exhibits dual mechanism nonlinear absorption.
TLDR
Photoluminescence and transient absorption studies of (L)Ir(ppy)(2)(+) carried out using 5 ns, 1064 nm pulsed excitation demonstrate that the same long-lived and strongly absorbing excited state can be efficiently produced by two-photon absorption.

Remarkable Photophysics and Amplified Quenching of Conjugated Polyelectrolyte Oligomers.
TLDR
Photophysics and fluorescence quenching of a series of monodisperse, anionic π-conjugated oligomers that are molecularly dissolved in aqueous solution reveal a structured fluorescence band with high quantum efficiency in water, in contrast to the low fluorescence quantum efficiency and pronounced aggregation displayed by structurally similar oligomeric and polymeric (phenylene ethynylene) conjugated polyelectrolytes studied previously.
