Abstract
We have synthesized a series of quaternized imidazo[1,2-a]pyridines in three steps from commercially available reagents. These compounds exhibit blue fluorescence emission at around 425 nm with good quantum yields. In addition, one specific compound was found to work as not only a two- and three-photon excitable mitochondria imaging agent, but also a therapeutic agent upon continuous irradiation conditions.

Abstract
Very large molecular two- and three-photon absorption cross-sections are achieved by appending ligated bis(diphosphine)ruthenium units to oligo(p-phenyleneethynylene) (OPE)-based "stars" with arms up to 7 phenyleneethynylene (PE) units in length. Extremely large three- and four-photon absorption cross-sections, through the telecommunications wavelengths range and beyond, are obtained for these complexes upon optimizing OPE length and the ruthenium-coordinated peripheral ligand. Multi-photon absorption (MPA) cross-sections are optimized with stars possessing arms 2 PE units in length. Peripheral ligand variation modifies MPA merit and, in particular, 4-nitrophenylethynyl ligand incorporation enhances maximal MPA values and "switches on" four-photon absorption (4PA) in these low molecular-weight complexes. The 4-nitrophenylethynyl-ligated 2PE-armed star possesses a maximal four-photon absorption cross-section of 1.8×10-108 cm8 s3 at 1750 nm, and significant MPA activity extending beyond 2000 nm.

Abstract
Three-photon luminescence (3PL) imaging with near-infrared (NIR) excitation is quite promising for its deep penetration, high resolution, and good signal-to-noise ratio (SNR). In this report, a type of red emissive fluorophore TPEPT with aggregation-induced emission (AIE) properties was synthesized, and it was found to possess a large three-photon absorption (3PA) cross-section of 6.33 × 10-78 cm6 s2 under 1550 nm femtosecond laser excitation. TPEPT was then encapsulated with mPEG5000-DSPE to form AIE nanoparticles, and the chemical stability, optical properties and toxicity were studied afterwards. TPEPT nanoparticles were then applied for 3PL in vivo vascular imaging of mouse brain under 1550 nm fs laser excitation, and a fine three-dimensional (3D) reconstruction with a depth of 500 μm was achieved.

Abstract
![]()
We present an implementation of single
residues for response functions
to arbitrary order using a recursive approach. Explicit expressions
in terms of density-matrix-based response theory for the single residues
of the linear, quadratic, cubic, and quartic response functions are
also presented. These residues correspond to one-, two-, three- and
four-photon transition matrix elements. The newly developed code is
used to calculate the one-, two-, three- and four-photon absorption
cross sections of para-nitroaniline and para-nitroaminostilbene, making this the first treatment of four-photon
absorption in the framework of response theory. We find that the calculated
multiphoton absorption cross sections are not very sensitive to the
size of the basis set as long as a reasonably large basis set with
diffuse functions is used. The choice of exchange–correlation
functional, however, significantly affects the calculated cross sections
of both charge-transfer transitions and other transitions, in particular,
for the larger para-nitroaminostilbene molecule.
We therefore recommend the use of a range-separated exchange–correlation
functional in combination with the augmented correlation-consistent
double-ζ basis set aug-cc-pVDZ for the calculation of multiphoton
absorption properties.

Abstract
We present the theory of three-photon circular dichroism (3PCD), a novel non-linear chiroptical property not yet described in the literature. We derive the observable absorption cross section including the orientational average of the necessary seventh-rank tensors and provide origin-independent expressions for 3PCD using either a velocity-gauge treatment of the electric dipole operator or a length-gauge formulation using London atomic orbitals. We present the first numerical results for hydrogen peroxide, 3-methylcyclopentanone (MCP) and 4-helicene, including also a study of the origin dependence and basis set convergence of 3PCD. We find that for the 3PCD-brightest low-lying Rydberg state of hydrogen peroxide, the dichroism is extremely basis set dependent, with basis set convergence not being reached before a sextuple-zeta basis is used, whereas for the MCP and 4-helicene molecules, the basis set dependence is more moderate and at the triple-zeta level the 3PCD contributions are more or less converged irrespective of whether the considered states are Rydberg states or not. The character of the 3PCD-brightest states in MCP is characterized by a fairly large charge-transfer character from the carbonyl group to the ring system. In general, the quadrupole contributions to 3PCD are found to be very small.

Abstract
Recent progress in developing various strategies for exploiting efficient MPA fluorophores for two emerging technological MPA applications including frequency upconversion photoluminescence and lasing as well as 2PA fluorescence bioimaging and biosensing are presented. An intriguing application of MPA frequency-upconverted lasing offers opportunity for the fabrication of high-energy coherent light sources in the blue region which could create new advantages and breakthroughs in various laser-based applications. In addition, multiphoton excitation has led to considerable progress in the development of advanced diagnostic and therapeutic treatments; further advancement is anticipated with the emergence of various versatile 2PA fluorescence probes. It is widely appreciated that the two-photon excitation offers significant advantages for the biological fluorescence imaging and sensing which includes higher spatial resolution, less photobleaching and photodamage as well as deeper tissue penetration as compared to the one-photon excited microscopy. To be practically useful, the 2PA fluorescent probes for biological applications are required to have a site-specificity, a high fluorescence quantum yield, proper two-photon excitation and subsequent emission wavelengths, good photodecomposition stability, water solubility, and biocompatibility besides large 2PA action cross-sections.

Abstract
Small three-photon absorption (3PA) cross-section values of present nonlinear organic molecules limit their practical applications. Although electron donors and electron acceptors have a great effect on 3PA cross-section, little is known about how the strength and situation of electron acceptors influence the 3PA cross-section value of a compound. The present work reports 3PA effects of two fluorene derivatives with symmetric D-π-π(A)-π-D archetype, which are named as 2,7-bis(4-methoxyphenylacetylene)-9-fluorenone (FATT) and 2,7-bis(4-methoxyphenylacetylene)-9-thoine-fluorene (TSATL). Large 3PA cross-section and ideal 3PA-induced optical limiting effects have been found in the two fluorene derivatives. The two molecules both have a different electron acceptor on the fluorene core, by which the 3PA cross-section value for FATT is enhanced by nearly 3-fold compared with that for TSATL. The mechanism of this significant enhancement in 3PA cross-section has been investigated by density functional theory (DFT) and configuration interaction singles (CIS) method with use of 6-311+G basis set in combination with conductor polarizable continuum model (CPCM). The theoretical results show that increase of electronegative character of the electron acceptor on the core is responsible for the increase of 3PA cross-section values of the two molecules.

Abstract
A bifluorenylidene derivative with extended π-conjugated system has been designed and successfully synthesized. The compound displays strong three-photon absorption effect. The obtained three-photon absorption cross section is as high as 81.3 × 10(-76) cm(6)s(2). Distinguished 3PA-induced optical limiting and optical stabilization performances have been achieved. The on-axis transmitted intensity approached a constant even though the incident laser pulse fluctuation was 300%.
