TL;DR:
The temperature effects on the spectral properties and photophysics of a new d(8)-d(8) dinuclear Pt(II) chromophore, [Pt(ppy)(mu-Ph(2)pz)](2), have been investigated and thermochromic shifts are tentatively ascribed to intramolecular sigma interactions between the two pseudocofacial d(z(2)) orbitals.

Biophysical Journal, 96(3), 437a.
TL;DR:
DHP clearly demonstrates the importance of the hydrophobic cavity as an inherent selector for substrates entering the distal pocket by making use of the cavity-halogen hydrophilic interaction concomitantly preventing non- Halogenated substrates from binding.

Nonlinear Photochemistry Squared: Quartic Light Power Dependence Realized in Photon Upconversion
The Journal of Physical Chemistry A, 113(33), 9266–9269.
Contributors: T. Singh-Rachford* & F. Castellano*
TL;DR:
Simultaneous two-photon excitation of a solution mixture of [Ru(dmb)3]2+ and 9,10-diphenylanthracene (DPA) using 860 nm light pulses from a Ti:Sapphire laser resulted in triplet energy transfer followed by triplet-triplet annihilation (TTA), ultimately leading to upconverted DPA fluorescence from the sensitized DPA triplets.

Contributors: T. Singh-Rachford* & F. Castellano*
TL;DR:
Low power visible-to-UV photon upconversion is demonstrated for the first time, achieved from two simple organic chromophores dissolved in benzene, and the TTA process was confirmed by the quadratic dependence of the upconverted integrated PPO emission intensity measured with respect to incident 442 nm light power density.
