248. Singlet fission contributes to solar energy harvesting in photosynthesis

Jenny Clark (University of Sheffield)

6/27/25, 9:00 AM

Invited talk

Photosynthesis, the foundation of most life, begins when sunlight is captured by (bacterio)chlorophyll (BChl) and carotenoid (Crt) pigments. These molecules are arranged so that captured energy migrates rapidly to reaction centres (RC), where it is stored as a charge separation. The complementary absorption of Crt and BChl pigments, and rapid energy transfer between them, underpins solar...

19. Deciphering the ultrafast photobehavior of benzothiadiazole-based HOFs and its molecular units: experimental and theoretical insights into their spectroscopic properties in solution and in the solid state

Abderrazzak Douhal (Universidad de Castilla la Mancha)

6/27/25, 9:30 AM

Contributed talk

Benzothiadiazole (BTD) derivatives have emerged as versatile building blocks for the fabrication of smart porous materials. Herein, we report on experimental and theoretical studies of two BTD-based H-bonded organic frameworks (HOFs) and their molecular units (MUs) in solutions and in solid state (BTIA and BTTA).1-3 The MUs in solutions exhibit a photoinduced intramolecular charge-transfer...

22. RF-compressed, THz-streaked ultrafast electron diffraction at high repetition rates with direct detection

Kasra Amini (Max-Born-Institut)

6/27/25, 9:50 AM

Contributed talk

Ultrafast electron diffraction (UED) [1-3] is a powerful tool for tracking the nuclear dynamics of photo-induced gas-phase reactions in real-time with picometre spatial and 150-240-fs temporal resolution [4,5]. However, time-resolving rapidly evolving photo-induced processes, such as photoisomerization [6] in vision (<350-fs predicted total timescale), remains challenging due to...

142. Linear and Ultrafast Optical Diffusion-Ordered SpectroscopY sheds new light on nanoparticles, amyloids, and mixed solutions

Giulia Giubertoni (University of Amsterdam)

6/27/25, 10:10 AM

Contributed talk

Linear and ultrafast optical techniques (including Raman, Infrared and Uv/Vis spectroscopy) are excellent tools to investigate molecular structure and dynamics in solution. However, these spectroscopic methods are generally not sensitive to the size of molecules. Inspired by concepts from NMR, we have developed a spectroscopic method that adds a size dimension to optical spectra: optical...
