	<span lang=\"EN-US\">A novel liquid dye 2-((2E,5E)-2,5-bis(4-(methyl(2,5, 8,11-tetraoxatridecan-13-yl)amino)benzylidene)cyclopentylidene)
malononitrile (TO-BDCM) was synthesized by incorporating two oligo(ethenyl
glycol) groups into the backbone of a prototype malononitrile derivative (BDCM)
for the purpose of increasing its solubility in organic solvents. The nonlinear
absorption properties of this liquid dye on 1064 nm ns pulsed laser were
investigated in DMF with remarkably high concentration up to ~<st1:chmetcnv unitname=\"m\" sourcevalue=\"1\" hasspace=\"False\" negative=\"False\" numbertype=\"1\" tcsc=\"0\" w:st=\"on\">1M</st1:chmetcnv>, showing a superior large nonlinear
absorption coefficient of <st1:chmetcnv unitname=\"cm\" sourcevalue=\"55.6\" hasspace=\"True\" negative=\"False\" numbertype=\"1\" tcsc=\"0\" w:st=\"on\">55.6 cm</st1:chmetcnv><sup>3</sup>/GW<sup>2</sup>.
Fairly good optical limiting and stabilization effects were achieved. Meanwhile,
the liquid dye exhibited equivalent stability under laser irradiation compared
to its prototype dye BDCM.</span>
