Abstract
Fluorescent probes with preferred photophysical properties have attracted considerable attention for their advantages in real-time and accurate detection of signalling molecules in living organisms. Nitric oxide (NO) is a ubiquitous cellular messenger closely associated with many physiological and pathological processes. A NO fluorescent probe, PYSNO, based on the pyridazinone (PY) scaffold with o-phenylenediamine as the receptor and thiophene (S) as the linker has been synthesized. Inspired by the experimental guidance, three other dyes (PYSSNO, PYSONO and PYONO) were theoretically designed by replacing the S linker with thieno[3,2-b]thiophene (SS), thieno[3,2-b]thiophene 1,1-dioxide (SO) and thiophene 1,1-dioxide (O) groups. The photophysical properties were theoretically investigated in aqueous solution, by the combined time-dependent density functional theory, polarizable continuum model and thermal vibration correlation function approaches. Our results indicate that the emission wavelengths of all the designed dyes show red shifts due to either an increase in the conjugation length or electron-accepting ability of the linkers compared to PYSNO. The photoinduced electron transfer (PET) processes are all absent in these systems. PYSSNO and PYSONO are theoretically expected to be promising candidates for novel NO fluorescent probes, but the suitability of PYONO as a NO probe is compromised by the predicted non-luminescent emission before and after reaction with NO. Our study not only offers valuable insights into the detailed structure-property relationships, but also opens a new avenue for the rational design of efficient fluorescent sensors for NO detection.

Abstract
Nitric oxide (NO) is an important signal molecule in biological systems and is correlated with many physiological processes and pathological diseases. To date, numerous fluorescent probes based on o-diamino aromatics have been designed and synthesized for NO detection utilizing the principle of photoinduced electron transfer (PET). However, the underlying PET mechanism has rarely been validated, and a systematic computational study on the photophysical properties is urgently desired. In this study, we used a theoretical protocol to comparatively investigate the sensing mechanism, photophysical properties and protonation effects of two emblematic probes NINO and PYSNO in aqueous solution, which combines a polarizable continuum model (PCM), time-dependent density functional theory (TD-DFT) and thermal vibration correlation function formalism (TVCF). Our findings reveal that the weak emission of NINO is due to activated PET with negative driving energy and blocked fluorescence with significant charge separation. In contrast, the poor luminescence of PYSNO is caused by the facilitated non-radiative dissipation, even though the fluorescence emission remains unobstructed. Although NINO has been successfully used in two-photon microscopy for detecting NO, we suggest that PYSNO possesses a superior two-photon absorption (TPA) cross section in the near-infrared region. The protonation effects suggest that both probes can function effectively in practical acidic lysosomal environments. Our study opens a new avenue for understanding the mechanism and predicting the properties of two-photon fluorescent probes for NO detection, thus aiding the rational design of efficient fluorescent sensors.

Abstract
Two-photon fluorescent probes with large two-photon absorption (TPA) cross sections have shown wide applications in biomedical domain. However, both the species and amounts of high efficient probes are far from meeting the requirements, one main reason is that the relationship between the molecular structures and the responsive mechanisms are not clear and theoretical framework in this field is not perfect. In this work, the photophysical properties including one- and two-photon absorption and emission of three newly synthesized fluorescent probes for hydrogen polysulfide (H2Sn) detection are investigated by density functional theory and time-dependent density functional theory with the polarizable continuum model in different solvents. Results indicate that the enhanced fluorescent intensity and enlarged TPA cross section can be found when the probes reacted with H2Sn. Moreover, the OPA intensity is largest and its fluorescent intensity is largely enhanced when detecting H2Sn for Pro2, this verifies its superior performance in the detection of H2Sn than Pro1 and Pro 3. Furthermore, the inner mechanism for the increase of TPA cross section is revealed, the responsive mechanisms for photo induced electron transfer (PET) and fluorescence resonance energy transfer (FRET) processes are revealed through analyzing the energies and distributions of frontier orbitals. Our calculations provide theoretical perspectives for experimental measurements and could sever as a useful reference for developing advanced probes in biomedical fields.

Abstract
Nonlinear optical properties of a series of newly-synthesized molecular fluorescent probes for Hg2+ containing the same acceptor (rhodamine group) are analyzed by using time-dependent density functional theory in combination with analytical response theory. Special emphasis is placed on evolution of the probes' optical properties in the absence and presence of Hg2+. These compounds show drastic changes in their photoabsorption and photoemission properties when they react with Hg2+, indicating that they are excellent candidates for ratiometric and colorimetric fluorescent chemosensors. Most importantly, the energy donor moiety is found to play a dominant role in sensing performance of these probes. Two-photon absorption cross sections of the compounds are increased with the presence of Hg2+, which theoretically suggests the possibility of the probes to be two-photon fluorescent Hg2+ sensors. Moreover, analysis of molecular orbitals is presented to explore responsive mechanism of the probes, where the fluorescence resonant energy transfer process is theoretically demonstrated. Our results elucidate the available experimental measurements. This work provides guidance for designing efficient two-photon fluorescent probes that are geared towards biological and chemical applications.
